Thus he has hitherto described the grace which is extended to us through the Gospel and the preaching of Jesus Christ, and has taught us how we should therefore conduct ourselves, namely: that we abide in a pure, inviolate mind of faith, since we know that no work that we can do or imagine, can at all help us: when such doctrine as this is preached, reason objects, and says, Ah! if that is true, I need not do any good work. And then the great heads fall foul of it, and from a christian condition, educe a freedom of the flesh, imagining they may do what they will. These St. Peter here meets, and anticipates them, and teaches how we are to use our christian freedom only towards God. For nothing more is needed but faith, to the end that I should give God the honor due Him, and embrace Him as my God, confessing that He is just, true and merciful; such faith sets us free from sin and all evil. If now I have made such a return to God, whatever time I yet live I am to live for my neighbor, so as to serve and help him. The greatest work that follows from faith is this: that with my mouth I should confess Christ, sealing that confession with my blood, and laying down my life for it, if so it be. Yet God does not need this work; only I am to perform it, that my faith may thereby be tried and known, so that others also may be brought to believe. Thereafter follow also other works, which must all be directed to this end, that I may thereby serve my neighbor,--all of which God must work in us; for it profits not that we should lead a carnal life and do whatever we please. Therefore St. Peter now says: V. 17-21. _And since ye call on the Father, who judgeth without respect of persons, according to every man's work, pass the time of your sojourning here in fear; and be aware that ye are not redeemed with corruptible silver or gold, from your vain conduct in the traditions of your fathers, but with the precious blood of Christ, as of an innocent and unspotted Lamb, who indeed was provided previously before the world began, but is revealed in these last times for you, who through Him believe on God, who raised Him from the dead, and hath given Him dominion, that your faith and hope might be in God._
